That makes sense, and seeing it laid out like this definitely helps me to understand the picture better, I hope it helps others too. I'll note that some of those uniques abilities lean really hard into the pillage-everything support aspect of skirmishers, and not into the direct-confrontation aspect, which is definitely a perception thing. They don't feel like they contribute damage despite being your super cool unique, even though they've completely wrecked a city's economy, and the base skirmisher is already fighting the same problem by gifting its damage to nearby units.
